dev-lang/php: new 5.6 and 7.0 revisions with bison dependencies.

The PHP build system checks for the presence of bison (even if it will
not be needed), and it emits a warning if an appropriate version is
not found. In the 7.0.x series, this is easy to address by simply
adding a newish version of bison to DEPEND.

In the 5.6.x series, however, there is a bug in the bison version
check. A warning is emitted even when a suitable version of bison
(>= 3.0.1) is present on the system. So in that series, we have added
>=sys-devel/bison-3.0.1 to DEPEND, but also added a new patch. The
patch disables the buggy bison version check, eliminating the
warning. There should be no danger in doing so now that a newer bison
is in DEPEND.

+Subject: [PATCH 1/1] Zend/acinclude.m4: don't warn about >=bison-3.0.1
+ versions.
+
+The PHP configure script will emit a warning if it thinks your bison
+version is insufficient:
+
+  WARNING: This bison version is not supported for regeneration of
+  the Zend/PHP parsers (found: 3.0, min: 204, excluded: 3.0).
+
+However, there is an error in the test that causes it to treat all
+3.0.x versions as if they were 3.0. The result is that users get
+warned about a perfectly acceptable version of bison.
+
+This patch is meant only for Gentoo, where we can require a working
+version of bison (something newer than 3.0.1). Having done so, this
+patch removes the check and the WARNING.
